Why Choose Broken Tractor:

  • ✅ Carraro Axle Specific Fit – Sourced specifically for the Carraro 2WD steering axle used across John Deere J, K, L, and P series backhoe loaders and 210-series landscape loaders
  • ✅ Small Part, Big Impact – A worn or missing Belleville washer allows king pin preload to drop, leading to front axle slop and accelerated bushing wear — replacing it is low cost and high value
  • ✅ Fast Shipping from a U.S.-Based Team – Processed and shipped quickly to get your machine back to work
